Knowing how much grass and silage you have available will influence feeding strategies now and into the autumn/winter, and any purchased feed buying decisions.
For a grazing system make sure you know how much grass you have available for cows, their demand and grass growth rates in order to plan your grazing policy.
Assessing tonnes of available silage is crucial in order to avoid a shortfall this winter, particularly if clamps have already been opened due to grass shortages. An easy calculation, shown below, can be used to work out the total volume of your silage clamp:
Volume = Length (L) x Width (W) x Height (H)
Estimate how many tonnes of silage your clamps are holding by using the following calculation, along with the forage density table provided above.
Tonnes = volume x density (see table) / 1000
